In running over the pages of our history for seven hundred years, we shall scarcely find a single great event which has not promoted equality of condition. The Crusades and the English wars decimated the nobles and divided their possessions: the municipal corporations introduced democratic liberty into the bosom of feudal monarchy; the invention of fire-arms equalized the vassal and the noble on the field of battle; the art of printing opened the same resources to the minds of all classes; the post-office brought knowledge alike to the door of the cottage and to the gate of the palace; and Protestantism proclaimed that all men are alike able to find the road to heaven. The discovery of America opened a thousand new paths to fortune, and led obscure adventurers to wealth and power.
